I'm wondering if anyone has had any success building the latest version of PHP as outlines at http://wiki.dreamhost.com/Installing_PHP5.
The most relevant script seems to be the one trying to install 5.3.8, but the script has several errors, most of which I was able to get through with modifications. Once everything was compiled, I modified the .htaccess file as prescribed but all I got were 404 - not found errors such as looking for /cgi-bin/php.cgi/phpinfo.php
The latest version of PHP is required by e-commerce sites for PCI compliance.
Edit: Nevermind. I used one of the older scripts and changed it for 5.3.9 and it works.
